6 Claims.

This invention relates to food-making machinery and refers more particularly to a device for kneading and shaping dough used for the making of snake-buns, loaves of bread, rolls or the like.

Heretofore it was necessary to employ either skilled workmen for this purpose, or it was necessary to use complicated and expensive machinery which could replace only a certain part of the necessary manual operations.

An object of the present invention is the provision of a comparatively simple and inexpensive machine used in the making of snake-buns, loaves of bread and the like, by means of which dough can be shaped and formed by entirely mechanical means.

Another object is the provision of mechanical means operating upon the dough and shaping and forming it in such manner that it is ready to be inserted into the baking oven in the form of snake-buns, loaves of bread and the like.

Other objects will be apparent in the course of the following specification.

The objects of the present invention may be 25 realized through the provision of a device comprising rollers through which the dough is passed so that it emerges in the form of a sheet or layer which is wound spirally by means of suitably arranged shafts or rollers. Suitable means are pro- 30 vided to cut the wound layers of dough at predetermined intervals to form snake-buns of a predetermined height.

The same or similar device can' be easily aadpted for the shaping of loaves of bread, rolls and the like.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings showing, by way of example, preferred embodiments of the inventive idea.

Figure? is an end elevation along the line 1-1 of Figure 3;

Figure 8 is similar to Figure 4 and illustrates the winding of the dough layers; 1

Figure 9 shows in front elevation a device used ;5 for forming dough intended to be baked into loaves of bread of standard size; and.

Figure 10 is a top view along the line I0I0 of Figure 9.

The machine shown in Figures 1 to 8 of the 10 drawings comprises a frame having four vertical supports 20, 2I, 22 and 23 (Fig. 1) carrying a horizontal endless sheet 21. 1

A device used tocontrol the volume of dough is situated substantially underneath one end of 15 the sheet 21. This device comprises two cutting discs 84a and 85 carried by a shaft 86 which is attached to the supports 22 and 23 by the two projections or angle irons 81 and 88. 1

Two pairs. of rollers are disposed above and below the shaft 86. The first pair of rollers 89 and 90 is rotatably mounted in the angle irons: 9| and 92 which are attached to the supports 22 and 23, respectively. A second pair of rollers 93 and 94 is situated below the rollers 89 and 90 and is rotatably mounted in the angle irons 95 and 96 which are also attached to the supports- 22 and 23. The positions of these rollers may be conveniently varied and adjusted, as shown in Figure 2.

As shown diagrammaticaly in Figure 1, the rollers 89 and 93 are driven by means of an endless belt or chain 91 which pass over a pulley 98 rotatable along with a shaft 99. The shaft 99 is driven by the motor 4|.

The device for winding the flat layers of dough is situated substantially below the pair of rollers 93 and 94 and comprises plates or walls I04 and I05 which are maintained in vertical predetermined positions by the distancing rods I06, I01, I08 and I09.

As shown more clearly in Figures. 3 to 8 of the drawings, eight shafts I I0 to H I are circumferentially disposed within a space I 3| between the walls I04 and I05 and are rotatably supported by these walls. Gear wheels I I8 to I25 are carried by the shafts IIO to H1, respectively, and mesh with a central gear wheel I25a which is rotatable along with a shaft I26. The shaft I26 carries a pulley I21 (Fig. 1) which is operated from the shaft 99 by means of a pulley I28 and an endless drive I29.

The transporting means used for moving the dough within the space I 3| surrounded bythe shafts III) to I I I in the direction of the arrow I32 shown in Figure 1, comprise a comb-like plate I30 provided with turned-up inclined blades I36 carrying a plurality of rotatably mounted gear wheels I33 (Figs. 3, 4, 6,7 and 8). The gear wheels I33 are rotated by a pinion shaft I34 which is driven by a gear wheel I35 (Figs. 1, 3, 5 and 6) meshing with the gear wheel I20.

When the transporting gear wheels I33 are rotated, they will grip the dough after it has been wound in the form of a roll illustrated in Figure 8, and will transport it in the direction of the arrow I32, shown in Figure 1.

Any suitable knife I361]. may be situated close to the outer surface of the plate or wall I94 and may be driven by a shaft I31 rotated by a motor I38 through the medium of gear wheels I39 and I49. The knife I35 is used to separate the rolled dough into snake-buns of predetermined length.

Furthermore, any suitable transporting device not shown in the drawings may be used for the purpose of transporting the snake-buns to a baking oven.

The described machine operates as follows:

The dough is placed upon the endless sheet 21 (Figure 1) and then the motor M is started.

The dough passes. between the two rollers 89 and 90 and also between the two rollers 93 and 94. Thus the dough acquires the form of a comparatively thin layer.

The rollers 89 and 93 are rotated in the same direction by the drive 91 which is operated by the motor 4!. The discs 84a and will cut or trim the edges of the layer of dough, preventing excess dough from entering and forming a pocket.

The first layer emerging from the space between the rollers 93 and 94 is guided by hand by the operator into the space I3I (Fig. 4) enclosed by the shafts H9 to H1, the layer being introduced between the shafts Ill) and I I1. Thegear wheels H8 to I25 (Fig. 5) of the shafts III) to H1 are rotated by the gear wheel I25a driven from the motor 4| by means of the endless drive I29.

Due to the rotation of the shafts I I 9 to I I1, the dough is wound within the space I3I in the form of a spiral (Fig. 8)

Due to the adhesiveness of the dough, it will continue to flow automatically from the space between the rollers 93 and 94 and into the space I31 as soon as the first original layers of the dough have been guided by the operator.

The gear wheels I33 carried by the comb-like plate I39 (Fig. 3) and driven by the pinion shaft I34, will engage the roller layers of dough and will shift them in the direction of the arrow I32 (Fig. 1) and through an opening provided in the plate I04.

The rolled dough is cut up into small pieces by the knife I36a and is transported to the baking oven.

The attachment shown in Figures 9 and 10 of the drawings is used for the manufacture of loaves of bread. The device for winding the layers of dough is substantially similar to the one described and comprises plates or walls I55 and I5I which are maintained at a distance from each other by the distancing rods I52, I53 and I54. Shafts I55 to ISI are carried by the plates I59 and I5I and are arranged along the circumference of a circle. These shafts are firmly connected with gear wheels I52 to I 68, which are driven by a central pinion I59 carried by the shaft I10.

The comb-like plate IN is firmly connected to the plates I59 and I5! and carries a plurality of small gear wheels I12. The gear wheels I12 are rotated by a pinion shaft I 13 which is rotatable along with a gear wheel I14 meshing with the gear wheel I64.

In this construction, as in the previously described one, the gear wheels I12 are used for shifting the dough in the direction from the plate I59 toward the plate I5I. The gear wheel I61 meshes with an idler gear I68a which, in its turn, meshes with the gear wheel I15. The gear wheel I15 is mounted upon an elongated shaft I16 similar to the one described. Layers of dough in-- troduced into the space enclosed by the shafts I55 to I5I are wound spirally therein due to the rotation of these shafts. The gear wheels I12 which are driven by the pinion shaft I13 will shift the rolled dough in a direction toward the plate I5I and will cause this dough to emerge through.

an opening formed in the plate I5I. The dough will be collected in the conical end I82 of the sleeve I19 and will pass through this sleeve while the sleeve is being rotated by the shaft I15. A knife I85 which is indicated diagrammatically in Figure 15, will operate at predetermined intervals to cut off pieces of dough. These pieces will then be ready to be introduced into a baking oven and baked into loaves of bread. v I

It is apparent that the specific illustrations shown above have been given by way of illustration and not by way of limitation and that the structuresv above described are subject to wide variation and modification without departing from the scope or intent of the invention, all of which variations and modifications are to be included within the scope of the present invention.
